Evaluating high performance communication

摘要

Recently, high speed interconnects capable of remote direct memory access (RDMA) such as InfiniBand and iWARP have gained considerable popularity due to their superb latency and bandwidth. Most existing studies about RDMA have focused mainly on its performance aspect. However, as power management has become essential for high-end systems such as enterprise servers and high performance computing nodes which are often equipped with RDMA capable network adapters, it is very important for us to take a fresh look at the benefits of RDMA from the power perspective.
